The Summit Sustainable Building Code requires energy and water efficient design and construction for residential and commercial buildings, helping our community meet important carbon reduction and water conservation goals.
Compliance with the 2020 Summit Sustainable Building code is required in the following jurisdictions:
- Breckenridge, Colorado
- Dillon, Colorado
- Frisco, Colorado
- Summit County, Colorado
Residential New Construction
All new residential construction will comply with the Department of Energy’s Zero Energy Ready Home program. This program applies to R-2 and R-3 occupancies as well as R-4 occupancies above 3 stories (but not more than 5 stories).
A Zero Energy Ready Home maximizes energy efficiency, air quality, and water conservation. The result is a home that’s more affordable to operate and healthy to live in. In fact, all certified Zero Energy Ready Homes are so efficient, a renewable energy system can offset most or all annual energy consumption.
Ready to build your first Zero Energy Ready Home?
- A list of all local HERS raters serving Summit County can be found here.
- The Department of Energy’s Zero Energy Ready Home Partner Central has everything designers and builders need to get started. First, you’ll have to register as a program partner and watch the Zero Energy Ready Home Orientation Webinar.
- Review the Zero Energy Ready Home program requirements. When designing a home, your architect should consult with a Home Energy Rating System (HERS) Rater early in the process to determine the required HERS score for your project. Builders will need to ensure that the building design and construction process meet the target score.
Commercial New Construction
New commercial construction must demonstrate 10% energy savings above a building built to the 2018 International Energy Conservation Code (IECC). In jurisdictions that have adopted the Summit Sustainable Building Code, the IECC has been amended to provide guidance on program requirements.
